•Self-repair of all database security vulnerabilities
|Database Backup||Automatic backup||Independent backups are possible, but the user has to find storage space and regularly validate the backup|
|Software and Hardware Investment||Pay-as-you-go, no software and hardware investment||Database servers are rather costly and the user must purchase their own SQL Server license|
|System Hosting||No hosting fee||More than RMB 5,000/year for each 2U server (more than RMB 10,000/year for two servers (master and slave servers))|
|Maintenance||O&M is not needed||Need to be maintained by DBA, greatly increasing OpEx|
|Deployment Resizing||Instant activation, fast deployment, elastic resizing, activated as necessary||Hardware procurement, data center hosting, and machine deployment are all required and can be time consuming|
|Rate of Resource Utilization||100% utilization rate, pay for what you use||Low rate of resource utilization, resources must accommodate peak traffic requirements|

|Hardware, Parts and Accessories||•Memory 1200 MB: 50 GB database, 600 IOPS.
•Price: RMB 2,040/year
|•The database cluster needs at least two servers with 600 IOPS, costing about RMB 6,000/set.
•One Intranet switch is used to connect the front-end web servers (the price of a cheap 1U non-NMS switch is about RMB 1,000)
•Additional 30% for replacing damaged hardware.
•Cost of hardware: (6000× 2+1000) x 130%= RMB 16,900
•Annual cost: RMB 16,900/3= RMB 5,633 (the cost of hardware is calculated according to a 3-year depreciation period)
|Data Center Hosting||There is no hosting fee as hosting is taken care of by a service provider.||The hosting fee of a 1U cabinet is RMB 3,000/year, and the hosting fee of two 1U servers and a 1U Intranet switch will be charged.Data center hosting fees: 3,000 x 3 = RMB 9,000|

However, when the ECS and RDS are in different regions, communication is done over the Internet which will incur Internet traffic fees.
